So, you state that the strut may have been installed at ant time by any previous owner, and you have you have no idea who installed the strut. Nevertheless you bad mouth all Boatyard’s.
I'm not sure what you are on about here, nor how to respond to such nonsense. This is a casual thread to vent about ****ty things that boat yards (or boat builders) do. If you have a problem with this and need to deconstruct my story then you can go sail somewhere else.
There is a chance that the strut itself was hand crafted by another PO, but I doubt it. Everything about this engine repower is ****ty, from the arrangement of the cables, the broken mounts, the shaft that was reused even though it is so long on the newer engine that it interferes with the rudder (took a chunk out of it this year and am fixing it now!), to the use of automotive wire, the sloppy butchery that was done to accomodate the new engine and make access, the fuel tank that was not fastened down, the non-stainless hose clamps (installed in 2006, no less). The list seems endless sometimes, and I'm just now getting to be able to fix the last few items after 1.5 years.
All this is the ****ty work of ONE boat yard on ONE boat. If you want to see a few ****ty things that boat builders do, on the other hand, check this link out!
Stoopid boat builder tricks
Edit: I'll just add that I'm not here to give you evidence. I'm just saying what I think happened and I'm keeping all the evidence to myself, because this is just a story about an anonymous yard. This isn't the right place to be asking for evidence, and to try and defend boat yards, because we all know full well that there are many crappy operations out there, and you either need to use one you really trust or do things yourself, and beware of engaging anyone else to do work on your boat.
